SPRAYER. 'i

SPECIFICATION forming part of Letters Patent No. 663,200, dated December 4, 1900.

Application iiled .Augustl 24, 1898. Serial No. 689,401. No modelo To all when?, t may concern,.-

Be it known that I, DE VANE B. SMITH, of Deerfield, in the county of Oneida and State ot' New York, have invented certain new and useful Improvements in Sprayers; and Ido hereby declare that the following'is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form part of this specification.

My present invention relates to improve; ments in sprayers; and the object of the invention is to provide a sprayer which effe@ tually atoinizes, distributes, and directs the spray and provides an instrument of sufcient capacity and effectiveness for practical use by agriculturists and dairymen and others having use for such a device.

The nature of the invention will appear in detail by the following specication an claim.

In the drawings, Figiire l shows a` perspective View of my improved sprayer. Fig. 2 shows a partial vertical section of the same. Fig. Sshowsapartialhorizontalsection. Fig. 4 shows a similar section to Fig. 3 of a modiiied form of construction.

Referring to the reference letters and figures in a more particular description, 1 indicates the sprayer barrel or cylinder, which receives the piston-head 2, mounted on the inner end of the piston-rod, which'rojd is provided on the outer end with a handle 4. Secured at one end of the cylinder 1 is a fluidreceptacle 5, provided with an opening 6, at which it may be filled. On the end of the cylinder l adjacent to the receptacle 5 is provided a cylinder-head 7. The cylinder-head 7, as shown in Figs. 1, 2, and 3, is provided with circular corrugations. In the head 7 there are provided air-discharge openings a, h b, c c. The opening a is arranged to discharge a blast from the cylinder, in line with the axis ot' the cylinder, as indicated by the dotted line emanating from this opening, as shown in Fig. 3. The openings b b are arranged in the edge of the corrugations of the head, so as to direct the air-blasts issuing therefrom at an acute angle with the axis of the barrel, as indicated bythe dotted lines emanating from these openings, as shown in Fig. 3. The openings c c are arranged in the edge of the corrugations of the head 7 at a greater angle from the axis of the cylinder, so as to direct the air-blasts issuing therefrom, as indicated by the dotted lines emanat-v ing from these openings, as shown in Fig. 3. It will be noted by reference to Fig. 1 that the several openings a, l) h, and c c are arranged in the same horizontal line across the head of the cylinder. From points approximate to the air-discharge openings a, b b, and c c extend a series of suction-tubes a', b' b', and c' c down into the fluid-receptacle 5 and to a point adjacent to the bottom thereof, as shown.

In the modified forni of construction shown in Fig. 4 in lien of the corrugated head 7 there is provided a curved or rounded head 7', in which are arranged the air-discharge openings a2, b2 b2, and c2 c2, all arranged to ldirect their blasts in diverging directions,

similar to the constructionshown in Fig. 3 and as indicated bythe dotted lines emanating from theopenings in Fig. 4. Similar snction-tubesaS, b3 h3, and c3 c3 are provided in connection with this form of cylinder-head, extending into a suitable receptacle, as shown in the other construction.

In operation the receptacle 5 is filled with asuitable liquid containing poisons for certain uses and`inedicated vfor certain other uses, as occasion may require. The'device is then operated by drawing'back the plunger by means of the handle 4, as indicated in dotted lines in Fig. 1, and then forcing it toward the head of the cylinder, forcibly expelling the air in divergent blasts from the openings in the head of the cylinder and across the top of the suction-tubes. The air-blast causes the fluids in the receptacle to rise in the tube and pass outof the upper end thereof, and when caught by the air-blast the tluid is atomized.

.The sprayer as a whole, by reason ot' ,the divergency of the openings, is delivered over a wide horizontal space and a comparatively narrow vertical space and in the most effective manner for ordinary use. The internal opening of the suction-tubes is comparatively IOO small, so that only a limited quantity of uid passes, which is effectively atomized and' not` delivered in globules or drops.

One o-r more 0f the air-discharge openings may be temporarily stopped or plugged and the spray or the manner in Which it is delivuses.

What I claim as new, and desire to secure by Letters Patent, is-

In a sprayer, a barrel having a curved or corrugated head having a-series of blow-holes arranged directly in the eurve or corrugations of the head toldeliver blasts of air in divergent directions, a plunger in said barrel, a Huid-receptacle vand. a Suction-tube for each blow-hole extending from a point approximate to the blow-hole into the receptacle,

yCombined, substantially as set forth. ered thereby modified to adapt it to various y VIh witness WhereofI have affixed my signa ture, in presence of two witnesses, this 18th day of August, 1898.
